Can You Fit 33 Inch Tires on a Triton (FITMENT GUIDE)

Fitting 33” tires to any off-road vehicle will enhance off-road capability, improve looks and offer better traction. Unfortunately, it’s not always a straight forward process and the requirements vary from vehicle to vehicle. This article will discuss what is required to fit 33” tires on a MN Triton.

In order to fit 33” tires to a MN Triton you will need the following:

  • 2-inch lift
  • Removal of front mud flaps
  • 16×8 offset wheel
  • Trimming of the upper plastic fender guards
  • Metal modification on the pinch weld.

Bigger tires is the single most effective method of gaining improved ground clearance. This is especially important for overcoming obstacles in an off-road situation. There are however a few limitations, especially when it comes to IFS (Independent Front Suspension) 4WD vehicles, such as with the Mitsubishi Triton.

Let’s now look at a few factors to consider when fitting 33” tires on your MN Triton, and the minimum requirements needed to accomplish this.

Fitting 33 inch tires on a ML Triton   

Let’s say from the outset that fitting 33” tires on a Triton is very possible, however not without a few modifications. When referring to 33” tires, we are looking at either a 285/75/16 or a 285/70/17 tire options. These sizes are the metric equivalent to 32.8” tires.

Let’s start with the minimum lift kit requirement.

Lift Kit

Before you even consider fitting 33” tires on your Triton, you’ll need to have a 2” lift kit installed. Even this isn’t enough, since you’ll still need to make additional modifications to prevent scrubbing at full lock. If you decide to go 3” or higher, beware there are serious implications to any IFS suspension, but more on that later.

However, it can be done. Should you fit 33” tires on your truck? There are mixed opinions when it comes to tire sizes, however, I give it a resounding YES! In fact I am currently running 33” tires on my truck and they work a treat! The added clearance, aggressive look, and improved traction and stability in my opinion is well worth it.

Let’s now look at the best wheel offset option for the Triton on 33’s

Wheel Offset

Wheel offset is always something that gets considered last, and it can become a complicated affair if you’re not sure exactly how much brake caliper clearance is needed.

It’s been widely agreed that 16×8 are recommended option here, however. 16×7 is apparently possible. Problem here is, you don’t want to go too negative offset on the wheels else you have too much wheel “poke” which causes other problems again. So with a 25+ offset the wheels will poke by 1cm or so. If you’re opting for allows over “steelies”, you’ll have more options available.

Backspacing is the distance measured from the hub mounting surface to the inside edge of the wheel. When you decrease backspacing, you gain more inside wheel clearance. There is a fine line between keeping the tyres in the guards and preventing scrub on arches, UCA, Brake calipers, etc.

Offset is measured in mm and generally refers to how your wheels sit inside the wheel wells. You get positive and negative offset wheels. When it’s positive the imaginary line is more towards the front and negative means the mounting surface is more towards the rear of the rim creating a deep dish effect.

Fender & Arch trimming

There are a few plastic sections on the inner fender guards that needs to be trimmed away since they will scrub at full articulation. So get your Stanley knife out and do some trimming of those wheel arch/guards where they are making contact. You’ll need to do some grinding of the inner guard pinch weld and trimming of the inside of the flare.

Fender trimming goes hand in hand with backspacing/Wheel offset as well as how wide the tire is. A wider tires will require more wheel arch clearance and room to move when flexing off-road and when turning at full lock.

When you squeeze oversized tires into a wheel arch without lifting the truck, you’ll need to trim away a lot of the inside fender and arch plastic to allow the tire to tuck behind the arch when turning and flexing off-road.

Will the 285/75/16 throw out your MN Triton speedo?

When you upgrade from a stock tire to one with a taller aspect ratio (Side wall), increasing the wheel circumference, your speedo can be thrown out. In this specific instance with the diameter being a 7.2% increase and a 15.1% increase in the aspect ratio, the speedometer will be thrown off slightly. The 7.2% increase in tire circumference means the actual speed will be higher by up to 6.5 mph @90mph

The below table will give you an indication of how the speedometer reading is affected.

Biggest Tires On A Stock MR Triton No Lift (FITMENT GUIDE)

The biggest tire you can fit on a MR Triton with stock suspension and stock rims are 235/85/16. This size fits without any rubbing problems, and no trimming or additional modifications are required to make them function properly.

Factory standard tires on the MR Triton is between a 245/70R16 or 245/65R17 or 265/60/18 which all roughly equate to 29.5”to 30.5” in metric sizes. The MR Tritons biggest downside is the lack of off-road clearance. If you ever intend on taking this vehicle off-road then it is highly recommended to invest in a quality 50mm lift kit. The best way to improve ground clearance and off-road ability is by fitting a larger set of tires.

Biggest Tires On A Stock MQ Triton No Lift (FITMENT GUIDE)

The biggest tire you can fit on a MQ Triton with stock suspension and stock rims are 265/65/17 or 265/70/16. They both equate to a 29.5” to 30.6” in metric measurements.  This size fits without any rubbing problems, and no trimming or additional modifications are required to make them function properly.

A 31.6” or 265/75/16 or 265/70/17 will be a very snug fit on a MQ Triton. Compared to the previous ML shape, the MQ Triton wheel arches and basic chassis design remained very similar. You could get away with this taller aspect ratio on-road, however there might be some scrubbing on the wheel arches when at full “flex” off-road. You will get conflicting opinions from tire retailers regarding whether 265/70/17 will fit without rubbing during suspension articulation.

With a bigger, heavier tire, you will also notice a slight reduction in all-round performance. It’s not a major difference and its barely noticeable most of the time in real-world daily driving, however if you know your truck well enough, you’ll notice a slight shift in its performance characteristics.

How much lift to fit 33” Tires on a Ford Ranger

f you want to fit a larger 33” tire without a suspension lift, there is some modification needed. The Ranger T6 crash bars protrude from the wheel well and the bigger 285/70/17 tire makes contact. These will need to be removed/modified first so as not to damage the new tires. They are quite a PITA to remove so be prepared. Once removed, and a 20+ offset aftermarket wheel is fitted you should be able to get the 33” tires to fit comfortably.

How much lift to fit 33” on a Jeep Wrangler

33-inch tires can be fitted to a stock Jeep Wrangler JK, but with minimum clearance on the front bumper and not enough clearance for full articulation off-road.

Before running out and fitting bigger tires to your JK, make sure you understand all the implications and that there are other factors that comes into play such as backspacing, clearance, fuel economy, handling and more.

To take full advantage of the Jeeps legendary articulation, you would do well to fit a 3-4” lift before fitting 33” tires.

Big lifts on an IFS Truck

When lifting a 4WD, the front suspension plays a major role in determining the complexity of the upgrade. In the case of a SFA or LIVE axle, the axle is separate or not fixed to the chassis. This allows you to fit big tires and higher lifts with a lot more ease. The CV angles are not compromised since they are always in line with the diff and axle.  This allows you to fit 3”, 4” and even higher with not much hassles. Fitting 33” tires to a Solid/Live axle truck requires less additional modifications and in most cases little to no Body or arch modifications.

An IFS front axle on the other hand is a more complex process and you are limited. Unfortunately most 4WD’s in production these days are IFS suspensions. Manufactures are more concerned about on road performance and safety so they produce IFS trucks which appeals to a larger market.

The main problem with IFS suspension upgrades are the CV axles. The diff of an IFS truck is mounted directly against the underside of the chassis. This makes for excellent stability and cornering, however, it limits the downward travel of the wheels and places the CV joints under more stress when the vehicle is lifted too high.

It’s not recommended to go higher than a 3-inch lift kit on an IFS vehicle, and if you do decide to go higher, you’ll need additional modifications such as diff drop kits, adjustable UCA (Upper Control Arms), LCA, and Stabilizer arms.


We have mentioned quite a few variables to consider before dropping a load on expensive over-sized tires. You should first determine what the primary application for the upgrade is. Is it purely for aesthetics or will you need maximum practicality, off road ability, while maintaining maximum articulation.
